| 中文摘要: |
| 以云南省草原基况监测成果、2022 年林草生态综合监测草原样地数据和国土三调数据为基础,对云南省现状草原类型、功能、利用方式、主要优势草种、生物量等因子进行分析评价。结果表明,全省现状草原共涉及9 个草原类型,总面积130.92 万hm2,其中山地草甸面积最大,占比38.42%;
主要功能用途为综合功能用途的草原面积占比76.06%;利用方式中面积最大的固土固沙草原面积占比为32.89%;主要原生天然优势草种为委陵菜属、野古草属、蒿属、黄茅属、薹草属、蕨类植物和白茅属;主要毒害草为紫茎泽兰、飞机草和狼毒类;年鲜草总产量为11.21×109 kg;热性草丛单位面积鲜
草产量最高,为10 338.17 kg/hm2;暖性草丛的物种丰富度和载畜量最高,为13.16 种、2.57 个羊单位。 |
| 英文摘要: |
| Based on the results of grassland base condition monitoring in Yunnan Province, grassland
sample data of comprehensive forest and grassland ecological monitoring in 2022, and the data of the third
national land survey, the types, functions, utilization patterns, main dominant grass species, biomass
and other factors of grassland in Yunnan Province were analyzed and evaluated. The results showed that
there were 9 grassland types involved in the province, covering a total area of 1 309 200 hm2, with mountain
meadows being the largest, accounting for 38.42% of the total area; the grasslands with comprehensive
functional uses constituted 76.06% of the total area; the largest utilization area was soil and sand fixation,
accounting for 32.89%; the dominant native grass species were Potentilla, Arundinella, Artemisia,
Heteropogon, Carex,Pteridophyta and Imperata; the main toxic and harmful grasses were Ageratina
adenophora, Chromolaena odorata and Stellera; the total output of fresh grass was 11.21×109 kg, with
the highest fresh grass yield per unit area found in hot-season grass communities at 10 338.17 kg/hm2;
the Warm-season grass communities exhibited the highest species richness and livestock carrying capacity,
with 13.16 species and 2.57 sheep units, respectively. |
